我有一個計時器類更新我的表,但我發現影響更改的唯一方法是使用此代碼。這實質上是一個休息時間應用程序。我正在使用ini4j來讀取網絡上的ini文件。它確實有效,但它正在與我正在做的其他事情一起創造速度問題。使用目前的設置,它可以或多或少地正確顯示時間,但當我添加更多人時會開始滯後。如果你的答案是學習jTables,這不會有幫助大聲笑。我無法使用jtables和fireupdate更改來實現這個功能。更新java表

這裏是我的表

},
new String [] {
"Analyst", "Time Started", "Timer", "Status"
}
));
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
JTableHeader header = jTable1.getTableHeader();
header.setBackground(SettingsIni.jtable1h());
header.setForeground(SettingsIni.jtable1ht());
jTable1.setBackground(SettingsIni.jtable1());
jTable1.setForeground(SettingsIni.jtable1t());
jTable1.setOpaque(false);
jScrollPane1.setViewportView(jTable1);
jScrollPane1.setOpaque(false);
jTable1.setFocusable(false);
//jScrollPane1.setBorder(BorderFactory.createMatteBorder(0,1,0,0,Color.black));
jScrollPane1.setBorder(BorderFactory.createEmptyBorder(0,0,0,0));
jScrollPane1.getViewport().setOpaque(false);
final Color jcolor1 = new Color(0, true);
jScrollPane1.getViewport().setBackground(jcolor1);
getRootPane().setBorder(BorderFactory.createEmptyBorder(0,0,0,0));//removed border
我加入這個代碼與表中的類的代碼。
@Override
public void tableChanged(TableModelEvent e) {
int row = e.getFirstRow();
int column = e.getColumn();
TableModel model = (TableModel)e.getSource();
String columnName = model.getColumnName(column);
Object data = model.getValueAt(row, column);
}
而且我在看這個添加到我的計時器,但它仍然感覺就像我失去了一些東西。
BreakTimev21.jTable1.tableChanged(new TableModelEvent(BreakTimev21.jTable1.getModel()));
從camickr我在我的tableupdate類中試過這個。仍然沒有幫助,它確實更新,但有點讓人毛骨悚然。我也記得用jTable1.setAutoCreateColumnsFromModel(false);
Object [][] data = {
{a1, StartIni2.one(), BreakIni2.one(), TypeIni2.one()},
{a2, StartIni2.two(), BreakIni2.two(), TypeIni2.two()},
{a3, StartIni2.three(), BreakIni2.three(), TypeIni2.three()},
{a4, StartIni2.four(), BreakIni2.four(), TypeIni2.four()},
{a5, StartIni2.five(), BreakIni2.five(), TypeIni2.five()},
{a6, StartIni2.six(), BreakIni2.six(), TypeIni2.six()},
{a7, StartIni2.seven(), BreakIni2.seven(), TypeIni2.seven()},
{a8, StartIni2.eight(), BreakIni2.eight(), TypeIni2.eight()},
};
String [] columnNames = {
"Analyst", "Start Time", "Timer", "Status"
};
TableModel model = BreakTimev21.jTable1.getModel();
((DefaultTableModel) model).setDataVector(data, columnNames);
我停止使用ini4j爲TABLEUPDATE的讀取部分,只是用java性能,這有助於witht他加快了很多,但仍然沒有解決。 setDataVector的工作原理與BreakTimev21.jTable1.setValueAt(StartIni2.one(), 0, 1);
一樣StartIni2現在使用java屬性而不是ini4j。
我能得到他們兩人的更新,但它仍然是緩慢的,它是罰款8行,但在16+它開始滯後。 – user1753429
我結束了不使用ini4j和公正使用java的道具,它的速度幫助很大,所以也許問題不在桌子上,不過你答對我最有幫助,謝謝! – user1753429
